To be honest I had not seen that before, my friend.  It is a strange one because I do not understand what is mean't by "what's the challenge in that"? Is there supposed to be some kind of challenge in producing an image within the Daz software?......If so, I have never come across it!

Maybe the writer had some kiind of problem producing Daz rendered images.....or, maybe the comment translation is wrong....I don't know, but it is odd!

Anyway, I much prefer using Reality simply because of the technicalities involved, now that does create a challenge for me.

And, your right about DS4 render engine.....boy, that is really beefed up.  I can make some very nice stuff using that....WITHOUT LIGHTING!!!
